Brad House	cafe6b37db	Add DNS record manpages (#615 ) The new DNS record parser and writer needs manpages. This PR implements those. Fix By: Brad House (@bradh352)	1 year ago
Ignat	7a140cb478	Randomize retry penalties to prevent thundering herd type issues (#606 ) The retry timeout values were using a fixed calculation which could cause multiple simultaneous queries to timeout and retry at the exact same time. If a DNS server is throttling requests, this could cause the issue to never self-resolve due to all requests recurring at the same instance again. This PR also creates a maximum timeout option to make sure the random value selected does not exceed this value. Fix By: Ignat (@Kontakter)	1 year ago

Brad House	0cc570eabe	Implement ares_reinit() to reload system configuration into existing channel (#614 ) This PR implements ares_reinit() to safely reload a channel's configuration even if there are existing queries. This function can be called when system configuration is detected to be changed, however since c-ares isn't thread aware, care must be taken to ensure no other c-ares calls are in progress at the time this function is called. Also, this function may update the open file descriptor list so care must also be taken to wake any event loops and reprocess the list of file descriptors.

Brad House	956b7ebf68	rewrite adig using new helpers (#607 ) adig previously performed manual parsing of the DNS records. Now it can focus strictly on formatting of output data for printing. It simply iterates across the parsed DNS packet and queries for the RRs, parameters for each RR, and the datatypes for each parameter. adig will now automatically pick up new RRs from the c-ares library due to the dynamic nature. The adig format also now more closely resembles that of BIND's `dig` output. A few more helpers needed to be added to the c-ares library that were missing. There ware a couple of minor bugs and enhancements also needed. Example: ``` ./adig -t ANY www.google.com ; <<>> c-ares DiG 1.21.0 <<>> www.google.com ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: RCODE, id: 23913 ;; flags: qr rd ra; QUERY: 1, ANSWER: 11, AUTHORITY: 0, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags: 0; udp: 512 ;; QUESTION SECTION: ;www.google.com.

Brad House	de323adfd5	make dns parser/writer public (#604 ) This PR makes the c-ares parser introduced in 1.21, and the new writer, along with associated helpers public. These helpers are contained in a new public header of `ares_dns_record.h` which should _not_ be included directly, instead simply including `ares.h` is sufficient. This will address #587, as well as #470. A follow-up PR will be made which will transform `adig` to use the new parsers and helpers. This PR does not currently add man pages for these public functions, that will be in a follow-up PR once the `adig` migration is done which may expose additional needed helpers. The two aforementioned PRs will be done before the 1.22 release. Fix By: Brad House (@bradh352)	1 year ago

Brad House	c433477753	Add SVCB and HTTPS RR (RFC 9460) (#603 ) This PR adds parsing and writing support for SVCB and HTTPS RRs as defined in RFC 9460. This should fix #566 Fix By: Brad House (@bradh352)	1 year ago
Brad House	df1cbdccf7	OPT RR should support parsing key/value options (#602 ) The OPT RR record has some seldom used options with a 16bit key and a binary value. The current parser and writer was not supporting this. This PR adds support. The same format is also used for SVCB/HTTPS records, so getting this in there is necessary to support that RR type. Also, we split the Binary record format into BIN and BINP, where BINP is an indicator that the binary data is _likely_ printable and will guarantee a NULL terminator. This is helpful for those attempting to print RRs. Fix By: Brad House (@bradh352)	1 year ago

Brad House	fb43c04bae	Add TLSA record support (#600 ) As per #470, c-ares is missing a parser for the TLSA record format (RFC 6698). This PR introduces that parser. Once the new parser interface becomes public and this PR is merged, then #470 can be closed. Fix By: Brad House (@bradh352)	1 year ago

Brad House	784ee5a754	DNS Record Write (#598 ) The `ares_dns_record_t` data structure created in the prior release is capable of holding a complete parsed DNS message and also provides all helpers in order to fill in the data structure. This PR adds write capabilities for this data structure to form a complete message and supports features such as DNS name compression as defined in RFC1035. Though this message writing capability goes further than c-ares internally needs, external users may find it useful ... and we may find it useful for test validation as well. This also replaces the existing message writing code in `ares_create_query()`, as well rewriting the request message without EDNS in ares_process.c's `process_answer()`.

Brad House	4ec6b5ce4c	Use EDNS by default (#596 ) All DNS servers support EDNS, by using this by default, it will allow larger responses without the need to switch to TCP. If by chance a DNS server is hit that doesn't support EDNS, this is detected due to the lack of the OPT RR in the response and will be automatically retried without EDNS.
